Kieth I have had several comp. cams go flat for no reason known other than bad hardening on the lobes,also comp cam will pay for this repair if you pressure them parts and labor, out of many engines built, all the cam failures were with comp cams, the rv cams in big block bowties are known for this. if you do replace just the bad parts you need to do a very good job of clean up just.002" will stop the lifter from turning and make the cam go flat on that lobe. also check for pushrods turning on breakin,any that are not turning could mean cam/lifter failure.
